Executive Summary
To support community capacity building and mobilization on issues of environmental justice and public health in the
Eastern Coachella Valley, The California Endowment invited UC Davis through a partnership with CIRS to partner with
local advocates in documenting the often-invisible patterns of cumulative environmental vulnerability in this region. In
response, this report gathers the latest available public
data sets for Riverside County and compiles them into

of a Cumulative Environmental Vulnerability Assessment
(CEVA). The CEVA reveals that residents in the Eastern
Coachella Valley face significant and overlapping environmental hazards and social vulnerability that far exceed those in the
Western Coachella Valley and the county as a whole. In particular, agricultural pesticide applications, drinking water quality,
and housing quality are key challenges to community well-being. The intention of this report is to help leaders better
understand and target increased investment in environmental protection, health promotion, and community well-being in
this sometimes forgotten but vital corner of California. The Eastern Coachella Valley represents an important opportunity
for developing innovative approaches to smart growth and regional equity that can support flourishing rural communities.
Revealing the Invisible Valley
On September 11, 2012, as the nation observed another tragic anniversary,
powerful storms brought the Eastern Coachella Valley, an often-forgotten corner
of Southern California, into sharp relief. Storm winds stirred up the stench of
decomposing organic matter from the depths of the dying Salton Sea, wafting all
the way to the Los Angeles basin. The same storms flooded many of the residential
mobile home parks of the Eastern Coachella Valley, further contaminating
drinking water supplies and overflowing already over-burdened septic systems.
For the primarily Latino, low-income working families inhabiting this expanse of
Riverside County, the state of emergency declared was just another in a long series
of chronic threats to their health and well-being that typically go unnoticed and
unaddressed.
Severe flooding in Mecca and Thermal submerged
homes, schools, and overwhelmed sewage and waste
water systems.
The Coachella Valley is a land of stark contrasts. The lush golf courses, exclusive
resorts, and celebrity sightings of the renowned Western Coachella Valley (WCV)
communities, such as Palm Springs, are worlds apart from the unpaved streets,
failing septic systems, and unauthorized waste dumps of the Eastern Coachella Valley (ECV). The ECV, as defined by local
advocates, includes the disadvantaged and environmental justice communities of Indio, Coachella, Thermal, Oasis, Mecca,
and North Shore, with a total population of approximately 88,000 residents, while the WCV extends from the northern
neighborhoods of Indio to Palm Springs and includes 324,000 residents (see Figure 1).
Across both the Eastern and Western expanse of the Coachella Valley, Native American populations from the Cabazon
Band of Mission Indians, Twenty-Nine Palms Band of Mission Indians, the Torres
Martinez Band of Cahuilla Indians, St. Augustine Band of Mission Indians, and
other tribes, steward the remains of ancestral lands (much of which had been
expropriated in earlier decades).1 Despite recent economic development initiatives
including several casinos, the majority of Native Americans in the region live in
poverty as does the indigenous Mexican population (including many Purhépecha
people).
Dead fish and noxious odors have degraded once

The concentrated poverty of the ECV contrasts with the significant contributions
by the hard working residents to the region’s and state’s vital agriculture, tourism,
and goods movement industries. The Coachella Valley (primarily the rural ECV)
is a major hub for agricultural production in Riverside County and California as a
whole, representing $526 million in gross agricultural value.2 The Coachella Valley
also attracts roughly 8.2 million visitors each year, including international and

domestic travelers to its many hotels, casinos, and
golf course resorts generating over $2.5 billion in
spending annually. Within the ECV itself, tourist
spending has been estimated at upwards of
$230 million annually (including the renowned
Coachella Music Festival).3 While most of the
Coachella Valley’s tourist attractions are located
in the WCV, many of the workers who power
this tourism economy commute from the
ECV.

don’t have worth. …You think

We’re human beings.”
While ECV residents have a strong pride of place, they also have considerable
concerns about the region’s environmental and health challenges. The
ECV is the site of chemical intensive agriculture, drinking water
contamination, and significant air pollution from interstate
traffic and the associated goods movement industry. Dump
sites and waste processing facilities also lace the area.4

because it’s Mecca…. Sure we’re in Mecca, but we’re not
animals. We’re human beings.”5
Limited air and water quality monitors,6 over-stretched
agency enforcement capacities, and large swaths of open land
with unregulated land uses keep many of these environmental hazards “off the map.” Checker-boarded Native American
reservation and trust land with sovereign tribal governments, and the many unincorporated communities that lack local
governments create a landscape of complex jurisdictions making coordinated environmental, land use and health regulation
challenging. Conflicts between some community advocates and local Native American tribes over environmental, land use, and
housing issues have begun to be resolved through collaborative forums.7 The non-citizen status of many residents (both legal
residents and undocumented residents) reduces the political
representation of the local communities. Recent elections of

power of local communities seeking environmental and social justice, including:
Eastern Coachella Valley Building Healthy Communities, Raices del Valle Youth
Empowerment Program, California Rural Legal Assistance’s Community Equity
Initiative on unincorporated communities, Pueblo Unido’s efforts in mobile home
parks, the Inland Congregations United for Change’s grassroots organizing, the
Environmental Justice Taskforce and its on-line environmental reporting system
IVAN, and environmental regulation by the Twenty-Nine Palms Band of Mission
Indians8 and other tribal governments that integrate western and cultural science.9
Building on these significant regional assets, the Coachella Valley represents an
important opportunity for developing innovative approaches to smart growth and
regional equity that can support flourishing rural communities.

Mapping for Environmental Justice
The methods used to create the CEVA are based on best practices
in the field (including the Environmental Justice Screening
Method10 and CalEnviroScreen developed by the California Office
of Environmental Health Hazard Assessment11) as well as input
from community partners about their highest priority social and
environmental challenges. The CEVA has incorporated several
important innovations to tailor this analysis especially to the
Coachella Valley.
• The pesticides indicator is comprised of the most toxic and
drift-prone chemicals including several that are applied more
heavily in this region.
• The pollution point source indicator uses a weighting method
Community partners contributed crucial local knowledge to
to score sites based on type, status, and activity, also accounting the mapping project.
for the incidence of multiple pollution points in a tract.
• The drinking water indicator is a ranking based on the six-year
average measurements of target chemicals with significant possible health effects in each tract.
• We have minimized the possibility for double-counting of toxic and hazardous waste sites by extensively cleaning the
data sets to eliminate duplicate records within and across data sets.
There are several limitations to the study methodology. We used census tracts as the unit of analysis. We were not able to
use the finer-grained census block groups in this analysis because the data are not reliable enough at this spatial level in such
largely rural areas. Census tracts are drawn to have a standard population range: therefore, there will be larger tract sizes in
areas with small and dispersed populations. A related effect of this approach in low population density areas is that all areas
of a tract are mapped with the same CEVA score, even if the environmental and/or social conditions are concentrated in
one area of the tract. This analysis also is not weighted for population, and instead shows the magnitude of the challenges,
not the number of people affected.
Other limitations include using data from the American
Community Survey, which has been shown to undercount key
populations prevalent in the ECV such as farm workers and
rural residents.12 Although we aggregate the data from water
quality measurements taken at the well level to the tract level
for the purpose of constructing the CEVA, it is important to
note that actual water quality is likely to vary across the tract.
We were not able to use water system polygons for a more
precise boundary and better linkage of well level data to sites
water consumption because these data were not available for
the entire county at the time of this study. We distributed
health data that are reported at the zip code level to the

a direct measure of health conditions in each census tract.
Lastly, several data sets could not be included in the CEHI;
most notably the CEVA does not include Particulate Matter (PM) because the air quality monitoring stations are located
too far from many census tracts in Riverside County, particularly in Eastern Coachella Valley, to allow for accurate data.

Cumulative Environmental Vulnerability Assessment: CEVA
The CEVA map demonstrates the interaction of the CEHI and SVI across Riverside County and highlights disparities
between places in the Coachella Valley using a simple color scheme (see Figure 2). In the CEVA map, the light gray color
designates census tracts in the lowest categories of CEHI and SVI, followed by the medium gray and yellow colored census
tracts signifying low to medium CEHI and SVI. The light orange colored areas identify the medium CEHI and SVI
categories.
The areas with the highest degrees of both CEHI and SVI are colored in dark orange, red, and crimson on the upper right
extent of the matrix. Residents in these dark colored areas on the map contend with both the highest relative levels of
environmental hazards and the fewest economic and/or social resources to avoid or mitigate these hazards. These areas
are considered Cumulative Environmental Vulnerability Action Zones (CEVAZ), to call out the need for strategic and
coordinated action to protect the community health and well-being. Nearly the entire ECV is included in the highest
combined CEHI and SVI, colored in crimson, therefore calling for the highest priority actions.

Issues behind the map
Limited health care access
A few, small health clinics are the only local options for those without health insurance (up to 70% in some communities13)
and the doctor-to-resident ratio is more than 4 times below the federally recommended level.14 Limited access to primary and
emergency care push many residents to travel across the border to Mexicali for health services and may also result in skewed
data on local health problems. Promotores de Salud, mobile health clinics, and other community-based health strategies
represent promising practices for increasing access and education.
Failing water infrastructure
Public water districts provide very limited service to rural residents. Many residents rely on private well water contaminated
by arsenic, lead, nitrates, chromium 6, and perchlorates. Residents of some mobile home parks with failing septic systems face
health risks from contact with raw sewage. Local advocacy and litigation have resulted in legislation supporting emergency
funding for water filtration systems and restitution for water overcharges. Pueblo Unido CDC is pioneering a reverse osmosis
water filtration system for ECV communities where municipal water is unavailable.
Gaps in public transportation
Limited bus routes, sidewalks, and bike lanes limit residents’ safe and affordable access to education, health services, employment,
and other important resources. County and regional transportation planning has tended to focus resources in the wealthier
WCV.15 A mismatch between the location of affordable housing and the location of low-wage jobs means that lower-income
people must commute far distances for work. Local advocates have prioritized equitable access to transportation as a top
regional priority.

Concentrated Hazardous Waste
Multiple hazardous waste treatment storage and disposal facilities dot the region, many next to schools and residences.
After noxious odors from a soil remediation facility at Western Environmental Inc. sickened students and teachers at a
nearby school, state and federal agencies restricted future operation.16 Constructive dialogue between the Cabazon Band
of Mission Indians, public agencies, and local advocates offers hope for future redevelopment of the site.
Unauthorized Dumping
Unauthorized dumping sites pervade the landscape. Lawson Dump and Mount San Diego are the largest of the originally
unauthorized sites in the region.17 Now closed, Lawson Dump’s remaining debris is over 50 feet high and with an
estimated one million tons of waste. Since 2006, the Torres Martinez Solid Waste Collaborative closed and cleaned
several major dumps and continues to crack down on unauthorized dumping on the reservation.
Inadequate and Unaffordable Housing
Lack of affordable and quality housing options and low-wage labor place decent housing out of reach for many in the
Eastern Coachella Valley. Many residents live in substandard trailers in mobile home parks with limited
infrastructure for safe drinking water, wastewater systems, paved roads, sidewalks and storm water
drainage. After Riverside County closed most private mobile home parks, a number of the remaining
mobile home parks are now on Native American lands with limited resources to meet the community’s
needs. Legal and community-based advocacy have increased availability of affordable housing and
have improved conditions in some parks. Further advocacy is necessary to ensure adequate funding
for housing development and improvements to mobile home parks.
Shrinking Salton Sea
California’s largest lake poses serious threats to regional air quality. Noxious stenches
have sickened nearby residents and spread up to 150 miles from the lake,
triggering hundreds of citizen complaints. Advocates fear that competing
pressures on the Salton Sea could lead to a drier lake further reducing
fish and wildlife habitat, increasing odors, and creating hazardous dust
affecting regional air quality, public health, agriculture productivity, and
tourism. Plans for new air quality monitors and habitat restoration may
help inform strategies to reduce the impacts on residents in the area
and beyond.18

Indicators
The key findings from this analysis include the following:
• The ECV has much higher rates of poverty, unemployment, and limited English proficiency as well as concentrations
of non-white residents compared to the WCV and the county as a whole.
• The ECV has much higher agricultural pesticide applications than the WCV and the county as a whole.
• The ECV has much higher concentration of impaired water bodies than the WCV and the county as a whole. There
are drinking water wells in the ECV with average chemical concentrations far above the state and federal Maximum
Contaminant Levels for arsenic, chromium 6, perchlorate, and nitrates.
In addition, some areas in the WCV, such as La Quinta, have elevated
levels of chromium 6. (See Figure 4.)
• While the drinking water quality from ECV wells is similar to that
in the WCV, the limited drinking water sanitation capacity in the ECV
amplifies the potential health impacts on ECV residents.
• Based on the high degrees of both Cumulative Environmental
Hazards and Social Vulnerability factors in the ECV, the vast majority
(81%) of area residents live in places that are considered Cumulative
Environmental Vulnerability Action Zones compared to the WCV
and the county as a whole.
• As indicated in Figure 2, there are portions of WCV that also
show high degrees of cumulative environmental hazards and social

From Research into Action
The extensive and overlapping environmental hazards and social vulnerabilities in the Eastern Coachella Valley may seem
overwhelming, but local residents and leaders have begun to develop a cohesive action agenda to improve conditions in
their communities. The Cumulative Environmental Vulnerability Action Zones (CEVAZ) identified here can serve as target
areas for coordinated action and investments by public agencies, elected officials, foundations, businesses, advocates, and
residents. No one entity or sector can accomplish this change agenda alone. Success will require new forms of collaboration
between all of these who are committed to a future for the Coachella Valley and rural California that is healthy, prosperous,
and sustainable. The following is an action framework that agencies and advocates in the region can use to develop specific
collaborative strategies to improve the health and well-being of the region.
Public Agency Action
State and Federal Government Agencies
• Prioritize mitigation, permitting, monitoring, and enforcement actions on
existing and potential future hazards to protect overburdened communities.
• Improve coverage of air quality monitoring, water quality testing, pesticide
drift monitoring, and identification of unregulated dumpsites to reveal the
region’s hidden hazards.
• Enhance consultation processes with the region’s sovereign tribal governments
to promote collaborative solutions to environmental management conflicts.
City, County, and Regional Government Agencies
• Utilize key planning processes and documents (community plans, housing, Senator Barbara Boxer and US EPA Regional Administrator
transportation, and economic development elements of general plans) Jared Blumenfeld listen to residents describe their
environmental justice challenges and demands.
to improve environmental and social conditions in the most vulnerable
communities, including unincorporated areas.
• Implement proactive infrastructure investment strategies to promote a healthy built environment through affordable, energyefficient, housing; drinking water testing and filtration, waste water management; community economic development;
transportation/ transit; and parks and recreation facilities to help build community opportunity, health and well-being.
All levels
• Enhance community engagement of the populations most at risk in the planning and decision-making on environmental,
health, and housing issues to increase community self-empowerment and collaborative relationships with public agencies.

From Research into Action
Community Organization Action
• Implement community participatory mapping to draw on unique local
knowledge and experiences to help put hidden hazards “on the map” and to
share “community treasures” of cultural wealth.
• Support leadership development and civic engagement with youth,
immigrants, residents of unincorporated communities, and other underrepresented populations to participate in solving the region’s economic,
environmental, and social challenges.
Small-scale drinking water purification systems
installed at mobile home parks by the Pueblo Unido
CDC are addressing this major threat to public health.
• Integrate environmental monitoring with existing research and community
engagement mechanisms such as the IVAN system and the Environmental
Justice Task Force to help build local capacity.
Private Sector Action
• Prioritize the recruitment and retention of good quality jobs (living wage, environmentally-friendly, and contributing
value to the local economy).
• Support job training to lend a “hand up” for low-wage workers, youth, and other under-served populations to gain access
to new and future high quality jobs.
• Partner with public agencies and community organizations to pursue federal, state, regional, and other funding resources.
Lifting Up the Invisible Coachella Valley
Young people are obscured by blowing dust on their way to school, part of the
multiple environmental and social challenges they face every day.
Youth leaders are taking action to promote a healthy and equitable future for their
communities.
By documenting the cumulative environmental hazards and social vulnerabilities in the Coachella Valley, this report has
revealed an often invisible, but vital part of California. The hard-working residents of the rural communities of the Eastern
Coachella Valley are seeking the resources and opportunities necessary to make their own lives, their desert region, and
the state as a whole, flourish. Supporting local residents to implement the action framework above will promote a future
where health, prosperity, sustainability, and equity are as clearly visible as the magnificent mountains that ring the valley.
